New pc build

[gamingguy27]

I have an AMD ryzen 2600 a gtx 1070 and ddr4 16 go ram but I don’t know what I get for windows 10? Do I do 64 bit or 32 bit?

 

[velocityg4]

64bit is required for 4GB or more RAM.

Also I have a semi modular PSU, is it normal that I didn’t use 2 plugs and including one that is attached to the PSU air self but everything is working correctly

I'm not sure what you're talking about. But the whole point of a modular PSU is you only use the cables you need and leave out the ones you don't.
